HJC i 71 Full Face Helmet - Semi Flat Black
(Product No.: BB-107H49.02)
HJC i 71 Full Face Helmet - Metal Black
The i71 pushes the boundaries for a Sport-Touring model with its new sleek shell design. The Advanced Polycarbonate helmet now has 3 shells throughout the 6 available sizes to help optimize weight and comfort for the rider. The rearranged top vent with enlarged mouth vents allows increased air intake and ventilation. Also new with the i71 are both face shield and sun visor. The HJ-38 Pinlock ready face shield comes with a new PE (Push/Eject) locking system for improved safety, yet still easy to use with gloves. The new sun visor (HJ-V12) provides a new 3-position option for the rider to adjust the sun shield forward (up to 10mm) delivering ideal sun visor protection. The i71 will also accept the second-generation Smart HJC Bluetooth systems.Find more products here
HJC Size Chart
HJC offers motorcycle helmets and bicycle helmets with partly different size ranges. The categories are therefore listed separately. Individual models may differ from the general reference chart; product-specific sizing always takes priority.
Motorcycle helmets – general HJC reference chart
Measure the head circumference with a flexible measuring tape around the head. For motorcycle helmets, HJC recommends measuring approximately 2.5 cm above the eyebrows.

Safety note: A size chart is a reference only. A helmet must fit firmly and evenly around the head, must not move out of position and should not create problematic pressure points. HJC warns that wearing the wrong helmet size can increase the risk of injury. Always try the helmet on and follow the product-specific fitting and safety instructions.
